Hang your files on the status bar to move them later (for MacOs). The files are not acually moved until you put them in the right place.

This feature can be found in many paid applications such as unclutter, filepane or dropzone. But FileHanger is a simple alternative offering just a way to temporarily put your file when you are moving them.
As you may see, FileHanger is open source, and the source code is quiet simple. There are few features I need to add such as taking into accound key modifiers to copy or move files accordingly. Do not hesitate to send a pull-request.
